Long-legged myotis records in Utah trace the state’s conifer forest belt: the Uinta-Wasatch-Cache, Dixie, and Fishlake national forests, each holding the loose bark and tree cavities this bat favors as summer roosts. It’s a fast, strong-flying hunter that keeps working cold nights long after most bats have quit, which fits its presence at higher, cooler forest elevations.

Utah’s 23 recorded sightings are heavily weighted toward midsummer, with July alone accounting for 10, well ahead of June and September at 4 each. Only three of those records came from iNaturalist; the rest are GBIF specimen and survey data, consistent with a species detected mostly through targeted bat surveys rather than casual sightings.

NatureServe ranks the long-legged myotis S3, Vulnerable, in Utah, a status worth weighing against how thin the observation record actually is.
